Recently the Bank has provided new indicators for monitoring the extent to which agricultural policies restrict international trade in farm goods. They come from two studies with differing methodologies and data sources, and each provides less-than-perfect estimates. This note shows how and...

To what extent has Sub-Saharan Africa’s slow economic growth over the past five decades been due to price and trade policies that have discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy distortions to relative prices...

This paper uses a new set of estimates of policy distortions to relative prices to...

A new set of estimates of policy induced distortions to relative prices is used to examine how they affect economic growth. We find that on impact there is no significant response of relative agricultural price distortions to changes in real GDP per capita growth of Sub-Saharan African...

Many fear China's accession to the World Trade Organization (WTO) will impoverish its farmers via greater import competition in its agricultural markets. We explore that possibility bearing in mind that, even if producer prices of some (land-intensive) farm products fall, prices of other...
